Description

Technical Field

[0001] This utility model belongs to the field of cooling bed moving beam technology, specifically relating to a novel cooling bed moving beam device. Background Technology

[0002] In steel rolling production in the metallurgical industry, the cooling bed is a key piece of equipment used for cooling, straightening, and conveying rolled high-temperature steel (such as rails and H-beams). Common cooling beds often employ a walking beam structure, whose core components include a fixed beam and a reciprocating moving beam. Driven by a drive mechanism (such as a crank connecting rod or rocker arm), the moving beam performs a rectangular motion of "rising-forward-falling-reverse," thereby lifting the steel and advancing it step by step.

[0003] In existing technologies, the moving beam and fixed beam are mostly integral structures, or even if there are protective plates, their connection methods are relatively complicated and not easy to replace quickly. When the surface in contact with the rail is worn, it is very difficult to repair or replace it. It often requires large-scale shutdown and long-term maintenance or even complete replacement of core components, resulting in extremely high maintenance costs and seriously affecting the production rhythm. Therefore, we propose a new type of cold bed moving beam device. Utility Model Content

[0004] To address the issues raised in the background section regarding the existing technology where the moving and stationary beams are mostly integral structures, or even with protective plates, their connection methods are complex and not conducive to rapid replacement, and when the surfaces in contact with the rails are worn, repair or replacement is extremely difficult, often requiring large-scale shutdowns and lengthy repairs or even complete replacement of core components, resulting in extremely high maintenance costs and severely impacting production schedules, this utility model provides a novel moving beam device for cooling beds.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a novel cooling bed moving beam device, comprising a fixed beam mechanism and a moving beam mechanism, wherein the upper end of the fixed beam mechanism is provided with a plurality of V-shaped grooves for bearing workpieces at equal intervals, and the inner sidewall of the V-shaped grooves is detachably fitted with a wear-resistant liner made of high wear-resistant material.

[0006] The fixed beam mechanism is provided with a moving beam mechanism on its inner side. The upper end of the moving beam mechanism is provided with several mounting slots at equal intervals. A wear-resistant liner made of high wear-resistant material is detachably installed in the mounting slot. Positioning plates are fixed on both sides of the upper end of the wear-resistant liner. The moving beam mechanism is provided with engagement slots on both sides of the upper end face of the mounting slot. Positioning bolts pass through the positioning plates.

[0007] As a preferred embodiment of the novel cooling bed moving beam device of this utility model, one end of the fixed beam mechanism is bolted with a connecting steel plate.

[0008] As a preferred embodiment of the novel cooling bed moving beam device of this utility model, the wear-resistant liner is detachably fixed to the inner wall of the V-groove by bolts.

[0009] As a preferred embodiment of the novel cooling bed moving beam device of this utility model, one end of the moving beam mechanism is connected to the rocker arm mechanism, and one end of the rocker arm mechanism is connected to the output end of the drive motor via a chain.

[0010] As a preferred embodiment of the novel cooling bed moving beam device of this utility model, the bottom of the wear-resistant liner is fixed with an insert block, and the bottom of the mounting groove is provided with a slot for positioning corresponding to the position of the insert block, and the insert block and the slot are in clearance fit.

[0011] As a preferred embodiment of the novel cooling bed moving beam device of this utility model, the positioning bolt passes through the positioning plate and presses it against the side wall of the engaging groove, thereby realizing convenient fixing and disassembly of the wear-resistant liner.

[0012] As a preferred embodiment of the novel cooling bed moving beam device of this utility model, the wear-resistant liner block and the wear-resistant liner plate are made of ultra-high molecular weight polyethylene.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: By setting independently detachable wear-resistant lining blocks on the moving beam mechanism and independently detachable wear-resistant lining plates on the fixed beam mechanism, this application is equivalent to setting two replaceable, highly wear-resistant protective shields between the core moving beam mechanism, fixed beam mechanism and expensive rail products. All friction and wear that may affect the surface quality of the rail are absorbed by these two protective layers of wear-resistant lining blocks and wear-resistant lining plates, ensuring that the surface in contact with the rail is always smooth, wear-resistant and easy to maintain. This fundamentally cuts off the path of the moving beam movement affecting the surface quality of the rail. With simple bolt connections, when any wear-resistant component wears out, maintenance personnel can complete the individual replacement in a short time without any complicated operations on the moving beam or fixed beam body. This prevents the problem of difficult maintenance caused by the fact that the moving beam and fixed beam in the prior art are mostly non-detachable integral structures. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Example 1

[0022] like Figures 1-4 As shown;

[0023] A novel cooling bed moving beam device includes a fixed beam mechanism 1 and a moving beam mechanism 5. The fixed beam mechanism 1 has several V-shaped grooves 3 equidistantly opened at the upper end for supporting workpieces. Wear-resistant liners 4 made of high wear-resistant material are detachably installed on the inner side wall of the V-shaped grooves 3. The moving beam mechanism 5 is arranged inside the fixed beam mechanism 1. Several mounting grooves 9 are equidistantly opened at the upper end of the moving beam mechanism 5. Wear-resistant lining blocks 8 made of high wear-resistant material are detachably installed in the mounting grooves 9. Positioning plates 10 are fixed on both sides of the upper end of the wear-resistant lining blocks 8. Engaging grooves 14 are opened on both sides of the upper end face of the moving beam mechanism 5 located in the mounting grooves 9. Positioning bolts 11 pass through the positioning plates 10.

[0024] In this implementation plan, by setting independently detachable wear-resistant lining blocks 8 on the moving beam mechanism 5 and independently detachable wear-resistant lining plates 4 on the fixed beam mechanism 1, two replaceable, highly wear-resistant protective shields are essentially set up between the core moving beam mechanism 5, the fixed beam mechanism 1 and the expensive rail products. All friction and wear that may affect the surface quality of the rail are absorbed by these two protective layers of wear-resistant lining blocks 8 and wear-resistant lining plates 4, ensuring that the surface in contact with the rail is always smooth, wear-resistant and easy to maintain. This fundamentally cuts off the path for the moving beam movement to affect the surface quality of the rail. With simple bolt connections, when any wear-resistant component wears out, maintenance personnel can complete the individual replacement in a short time without performing any complicated operations on the moving beam or fixed beam body.

[0025] In an optional embodiment, a connecting steel plate 2 is bolted to one end of the fixed beam mechanism 1.

[0026] In this implementation plan: the connecting steel plate 2 facilitates the receiving of steel materials.

[0027] In an optional embodiment, the wear-resistant liner 4 is detachably fixed to the inner wall of the V-groove 3 by bolts.

[0028] In this implementation plan: when the wear-resistant liner 4 wears out due to long-term friction with high-temperature steel rails, maintenance personnel do not need to replace or repair the entire expensive fixed beam mechanism 1. They can simply remove the bolts to take the worn wear-resistant liner 4 out of the V-groove 3 and replace it with a new one, which reduces maintenance costs and shortens downtime.

[0029] In an optional embodiment, one end of the moving beam mechanism 5 is connected to the rocker arm mechanism 6, and one end of the rocker arm mechanism 6 is connected to the output end of the drive motor 7 via a chain.

[0030] In this implementation scheme: the drive motor 7 serves as the standard power source, transmitting power to the rocker arm mechanism 6 via a chain, which in turn drives the moving beam mechanism 5 to perform precise stepping motion. The transmission method is mature, reliable, and easy to apply and maintain.

[0031] In an optional embodiment, the bottom of the wear-resistant liner 8 is fixed with an insert 12, and the bottom of the mounting groove 9 is provided with a slot 13 for positioning corresponding to the position of the insert 12. The insert 12 and the slot 13 are in clearance fit.

[0032] In this implementation plan, the design of the insertion block 12 and the slot 13 provides a quick and accurate initial positioning when replacing the wear-resistant liner 8. During installation, the operator only needs to align the insertion block 12 with the slot 13 and insert it to ensure that the wear-resistant liner 8 is in the correct basic position in the horizontal direction, thus preparing for subsequent tightening.

[0033] In an optional embodiment, the positioning bolt 11 passes through the positioning plate 10 and presses it against the side wall of the engagement groove 14, thereby enabling convenient fixing and disassembly of the wear-resistant liner 8.

[0034] In this implementation scheme: by tightening the positioning bolt 11, the positioning plate 10 is firmly pressed against the side wall of the engagement groove 14 by the clamping force of the bolt, thereby restricting the movement of the wear-resistant liner 8 in the vertical direction and preventing it from loosening and falling off due to vibration or impact during operation.

[0035] In an optional embodiment, the wear-resistant liner 8 and the wear-resistant liner plate 4 are made of ultra-high molecular weight polyethylene.

[0036] In this implementation plan: Ultra-high molecular weight polyethylene is selected as the material for wear-resistant liner 8 and wear-resistant liner plate 4. Its wear resistance is higher than that of many metals, which can significantly extend the service life of wear-resistant parts. It has an extremely low coefficient of friction, which is equivalent to providing a self-lubricating surface when in contact with the rail, which can minimize frictional damage to the rail surface and is crucial for protecting the quality of the rail surface.

[0037] Working principle:

[0038] In the initial static state, the drive motor 7 is not started, the rocker arm mechanism 6 is in the initial position, and the moving beam mechanism 5 is located at the lowest point of its motion trajectory. At this time, the high temperature steel rail is supported by the V-groove 3 at the upper end of the fixed beam mechanism 1. The wear-resistant liner 4 is detachably installed on the inner wall of the V-groove 3 by bolts. The steel rail is in direct contact with the smooth wear-resistant surface of the wear-resistant liner 4, rather than the body of the fixed beam mechanism 1, forming the first layer of surface protection.

[0039] During the lifting phase, the drive motor 7 starts and drives the rocker arm mechanism 6 to swing via the chain, pushing the moving beam mechanism 5 to rise vertically. When the moving beam mechanism 5 rises, the upper surface of the wear-resistant liner 8 set in the upper mounting groove 9 contacts the bottom surface of the rail. As the direct contact part and sacrificial part between the moving beam mechanism 5 and the rail, the wear-resistant liner 8 has high wear resistance to ensure that no debris or scratches are generated due to friction during the lifting process, thereby ensuring the quality of the bottom surface of the rail. The moving beam mechanism 5 body does not contact the rail at all and is effectively protected.

[0040] During the step-by-step transfer phase, the moving beam mechanism 5 carries the wear-resistant liner 8 and the rail horizontally for one step. During this process, there is no relative sliding between the rail and the wear-resistant liner 8. The wear-resistant surface of the wear-resistant liner 8 continuously provides protection, achieving lossless transport. During the descent and placement phase, the moving beam mechanism 5 descends and places the rail back into the V-groove 3 of the fixed beam mechanism 1 at the next station. The wear-resistant liner 4 receives the rail. The wear-resistant surface of the wear-resistant liner 4 ensures that the rail will not be scratched during placement and static cooling. Then, the moving beam mechanism 5 descends to the lowest point and returns to prepare for the next cycle.

[0041] When the wear-resistant liner 8 is worn to the point of needing replacement, the maintenance personnel only need to use tools to loosen the positioning bolt 11 to disengage it from the locking groove 14, and then lift the wear-resistant liner 8 upwards. When installing the new wear-resistant liner 8, first align the insert 12 with the insertion slot 13 to achieve initial positioning, then press the positioning plate 10 into the locking groove 14, and tighten the positioning bolt 11 to complete the fixation. When the wear-resistant liner 4 is worn to the point of needing replacement, the maintenance personnel only need to remove the bolts that fix it to the side wall of the V-groove 3 to remove the old wear-resistant liner 4, replace it with a new one, and then tighten the bolts again.

[0042] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
